Abstract

The utility model discloses a quick connector for a hose. The quick connector comprises a connector body, a one-way valve and a hose locking mechanism. The hose locking mechanism is located at the butt joint end of the connector body. The hose locking mechanism comprises a hose clamping piece and a C-shaped spring. A dowel penetrates through a positioning hole in the hose clamping piece and enables the hose clamping piece to be fixed to the butt joint end of the connector body. The C-shaped spring is wrapped on the outer side of the hose clamping piece, and the tightness degree of the hose clamping piece is realized through deformation of the C-shaped spring so that a locking mechanism for the connection end of the hose can be formed. According to the quick connector, on one hand, the hose locking mechanism is used for realizing quick connection of the hose, the pipeline connection time is shortened greatly, and work efficiency is improved; on the other hand, the one-way valve is installed inside the connector, secondary maintenance and installation of the pipeline is avoided, and the cost is reduced.

Description

A kind of gladhand

Technical field

The utility model relates to a kind of gladhand, divides and belongs to pipeline connection technology field by International Patent Classification (IPC) (IPC).

Background technique

Whether hose coupling belongs to a kind of connector, is mainly used in being connected between tube and tube, can make first wherein fluid along Flows, second in blackout process, can realize fast and accurately and installing.The structure of existing hose coupling is mostly, one hollow conduit, these hollow conduit two ends are connected with flexible pipe respectively, and in existing flexible pipe, mostly there is better sealing, be the important courteous of hose construction design but install fast and accurately, and be the formation of pegging graft manually mostly for existing hose coupling, use for a long time, cause connecting the situations such as not tight, directly affect the production and operation, thereby raise the cost; In existing hose coupling, be mostly simultaneously and realize two-way fluid and flow, if desired one-way flow need to add check valve body on pipeline, from and further increase cost.

Thus, the inventor considers existing hose coupling to improve, and this case produces thus.

Model utility content

For the deficiencies in the prior art, the utility model provides a kind of gladhand, and it utilizes flexible pipe locking mechanism, realizes the quick connection of flexible pipe, thereby greatly reduces the pipeline connect hours, thereby increase work efficiency; On the other hand, in one-way valve installation and joint, thereby avoid the secondary of pipeline to repair dress, thereby reduce costs.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of gladhand, this joint comprises adapter body, one-way valve and flexible pipe locking mechanism, wherein:

Adapter body, it is the hollow tubular with holding cavity;

One-way valve, it is positioned at the holding cavity of adapter body, forms and has the joint structure of controlling direction of flow;

Flexible pipe locking mechanism, it is positioned at the butt end of adapter body, this flexible pipe locking mechanism comprises hose clip gripping member and C type spring, one pin passes the positioning hole in hose clip gripping member and hose clip gripping member is fixed on adapter body butt end, and described C type spring is wrapped in the outside of hose clip gripping member and utilize the deformation of C type spring to realize the degree of tightness of hose clip gripping member, thereby form the locking mechanism to flexible pipe connecting end.

Further, described C type spring is open C type spring.

Further, described hose clip gripping member comprise two be hinged by bar, this two by bar one end by pin and be articulated on this pin the scissor switching structure forming taking pin as axle.

Further, described two are arcuate member by bar, press bar pivot joint for these two, thereby formation center have the linkage structure of circular butt hole.

Further, describedly eachly stretch out in adapter body outside by bar one end and form manually-operated press-button structure.

Further, described adapter body is stepped, this adapter body two ends diameter difference, and one end that diameter is large is butt end, and the little one end of diameter is bayonet end.

Further, described bayonet end week side indentation, and each teeth arrange towards the butt end direction of adapter body, thereby form sealing configuration.

Further, described one-way valve is positioned at the holding cavity of adapter body, and between one-way valve and holding cavity inwall, is provided with seal ring, and sealing circle is embedded in the groove in one-way valve outside.

Further, described one-way valve is all valve bodies of realizing one-directional fluid flow.

Advantage of the present utility model:

1, the utility model has designed flexible pipe locking mechanism in the butt end of adapter body, realizes the quick connection of flexible pipe, thereby greatly reduces the pipeline connect hours, thereby increase work efficiency;

2, the utility model has also designed the holding cavity of stepped adapter body inside, and one-way valve is installed in this holding cavity, realizes the one-way flow of pipeline inner fluid, thereby avoids the secondary of pipeline to repair dress, thereby reduce costs.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment: refer to shown in Fig. 1 to Fig. 3, a kind of gladhand, this joint comprises adapter body 1, one-way valve 2 and flexible pipe locking mechanism 3.

Refer to shown in Fig. 1 to Fig. 7, aforementioned adapter body 1 is for having the hollow tubular of holding cavity 11, described adapter body 1 is stepped, this adapter body two ends diameter difference, one end that diameter is large is butt end 12, and the little one end of diameter is bayonet end 13,13 weeks side indentations of described bayonet end, and each teeth arrange towards the butt end direction of adapter body, thereby form sealing configuration.

Refer to shown in Fig. 1 to Fig. 7, aforementioned one-way valve 2 is positioned at the holding cavity 11 of adapter body, and between one-way valve 2 and holding cavity 11 inwalls, be provided with seal ring 21, sealing circle 21 is embedded in the groove 22 in one-way valve 2 outsides, formation has the joint structure of controlling direction of flow, and described one-way valve 2 is for realizing all valve bodies of one-directional fluid flow.
